How to load comtrade data .cfg-.dat

Hello, I installed the necessary packages with NuGet, but I cannot import the Comtrade files(.dat and .cfg). I tried different ways with .Net and .NetFramework, can anyone give me an example code to open the files for c# winform or windows form app?

Here is a fairly simple example of code that reads from a COMTRADE file using the GSF.COMTRADE library. It just reads the timestamps and values into a collection of ParsedChannel objects to be used for populating a chart.
